BAG-HOLDER.

Specification of Letters Patent.

Application filed July 29, 1915. Serial No. 42,555.

To all whom it may concern Be it known that I, HARRY R. CONKLIN, a citizen of the United States of America, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Bag- Holders; and I do hereby declare the folto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters or figures 0, reference marked thereon, which form a part of this specification.

My invention relates to bag holders, and more particularly to the holders of the strainer or filter bags used in the recovery of precipitates obtained in. the extraction of precious metals by the cyanid process, where the suspended precipitate is supplied under pressure or under a liquid head; or to the holders of other types of bags for the recovery of fume, oxids, &c., of other industrial processes.

The object of the invention is to construct such a holder that the'bag can be readily placed thereon and retained in position by a suitable element and subsequently tightly secured by suitable means ready for use.

Referrin to the drawings, in which like parts are similarly designated-Figure 1 is a side elevation of a bag holder embodying my invention, and showing the upper end of a bag connected thereto; Fig. 2 is a vertical central section of Fig. 1. Fig. 3 is a detail plan view of a portion of the retaining band or ring, and Fig. 4: is a like view of a portion of the securing band or ring.

The bag holder comprises a plate or cast ing 1, having an outer flange 2, and an inner flange 3. The inner flange 3 is provided with a threaded perforation or bore l for the reception of the threaded end of a supply pipe P, which pipe is usually provided with a suitable closing valve above its threaded end.

In the periphery of the plate or casting 1 is a groove 5, here shown as substantially semicircular in section, and into this groove fits a retaining band or ring 6, split and having overlapping ends, as shown at 6, Fig. 3.

The bag B is here shown of double thickness, the inner thickness of muslin and the outer thickness of heavier material, as canvas to support the thin inner bag against internal pressure. Anyother type of bag may be used.

The mouth of the bag B is slipped over the plateor casting 1, and the split retaining ring 6 sprung over the fabric, so as to retain the fabric between said ring and groove. 'A clamping ring, Fig. l, is then placed over the retaining ring, and forced tightly together, causing the retaining ring 6 to so tightly clamp the fabric of the bag B in the groove 5, that a liquid or gas tight joint is formed. This clamping ring, Fig. 4, comprisesv a flat ring 7 split, as shown at 8, so as to provide overlapping ends. On one end of the band is riveted or otherwise secured a pivot support 9 for a pivot or hinge-pin 10. Mounted on the pin 10 is the eye 11 of bolt 12, whose opposite end passes into a slot. 13 in a compression or forcin member 14 iastened on the other end oi said clamping ring 7.

A thumb-nut 15 or equivalent, screws on the threaded end 16 of the bolt 12 and bears against the forcing member to draw the overlapping ends of the band '7 together, and cause the retaining ring to exert the requisite compression to make a liquid tight joint between the bag and the plate 1.

When the bag is full it is unscrewed from pipe P and hung on a hook that passes through the central supply orifice at and engages the under side of the plate 1 beyond the flange 8, into the annular recess formed between the flanges 2 and 3, said flange 3 preventing the plate from slipping oil of the hook.

I claim-- 1. A bag holder comprising a plate having a central supply orifice and a peripheral groove, a retaining band cooperating with said groove to retain a bag between said plate and groove, and a securing band placed over the retaining band.

2. A bag holder, comprising a plate having a supply orifice and a peripheral groove, a split retaining band having overlapping ends and fitting into said groove, a split securing band having overlapping ends fitting over said retaining band and means to draw the ends of the securing band together.

3. A bag holder comprising a supporting plate for engagement by the mouth of the bag, said plate having a supply orifice and means for the attachment of a filling tube 4. A bag holder comprising a plate having a peripheral groove and a supply orifice a retaining band cooperating with sai groove, a split securing band cooperating with said retaining band, a bolt pivoted on one end of said band, a nut on, said bolt, and a slotted forcing member on the other end. of-said band engaged ,by's aid bolt and nut. 7 I

5. A bag holder comprising a supporting plate for engagement by the'mouth of the 15 bag, said plate having a supply orifice, and means for the attachment ofa filling tube and provided with means integral with sai plate. and forming an annular recess between said orifice and the periphery of the 20 plate for engagement by a lifting and s 11p porting member.

In testimonythat I claim the foregoin as my invention, I have signed my name.

HARRY R. CON'KLIN.
